The differences between normal and papillary, normal and anaplastic and papillary and anaplastic thyroid biopsies were statistically significant (p<0.05), thus confirming that FUCA-1 expression levels were more than twice in PTCs compared with ATCs also by measuring the FUCA-1 mRNA levels (Figure 3A). Here, FUCA1 is linked to Ehlers-Danlos syndrome, musculocontractural type.
